Figure 4From: Analysis of Approximations and Aperture Distortion for 3D Migration of Bistatic Radar Data with the Two-Step ApproachMigration aperture with the two-step approach for the rms (a) and the LLNL (b) approximations at four different target depths. The antenna-medium distance is 10 cm; the radar wave velocity into the medium is 12 cm/ns; the TX-RX distance is 14 cm with the azimuth oriented in the y-direction.Back to article page
